PROCESSES
Student: Michailo HUDYMSpecialty: Economic cybernetics Scientific supervisor:Doctor of Engineering, Full Professor Yu. K. Taranenko
Dnipropetrovsk 2014
THE PURPOSE
is to examine the system and explore dynamic development of the models of the economic objects through the operational calculus.
The novelty of the results
consists in improvement of the economic models, especially for decision-making due to forecasting methodology.
TASKS OF THE DIPLOMA RESEARCH
to analyze operational calculus for cyclic processes in the economy;
to create a predicting model using modern tools (software);
to justify solutions to management problems in real time;
to assess the models;
to use methods of operational calculus.
:
THE OBJECT OF THE INVESTIGATION
THE SUBJECT OF THE INVESTIGATION
is the complex tools of operational calculus and its form in computer programs.
is economic systems which have dynamic and cyclical nature of development at any levels.
THE MAIN SIMPLE UNITSA proportional unit
An accumulation unit,reversibly - a differentiating unit
A discrete delay unit
An inertial delay unit
A unit of the sum
STRUCTURAL TRANSFORMATION OF UNIT CONNECTIVITY
to analyse series connection to analyze parallel connections
to analyze feedback connection
THE MAJOR USED TRANSFORMATION INVESTIGATED
A SAMPLE OF THE TRACKING SYSTEM
MODIFIED DYNAMIC SIMULINK MODEL OF PREDICTION
PROPERTIES OF THE MODIFIED DYNAMIC SIMULINK MODEL OF PREDICTION
Additional parameters were added that are based on the theory of investigation of operational calculus.
The modified model is simple in use and based on the theory of the ecological and economic «Predator-Prey» model.

THE MAIN SOLVED TASKS OF THE MODEL
The created model can: show the cycle of the capital in time;
show the impact on the input of any transfer function;
identifying errors from reality;
show the dynamics generating an economic cycle.
